Can DRM40 DIN rail redundancy modules deliver peak power ratings?

Many industrial loads draw peak loads for short durations of time. This can occur when a DC motor is first turned on, for example. A power supply capable of providing a peak current is smaller and more cost effective than using a higher rated model that can deliver the peak current continuously.

The DRM40 series of 20-40A DIN rail redundancy module can deliver a peak current of up to 150% of the rated current for up to 4 seconds with a duty cycle of 35% for use with capacitive and inductive loads.

However, care must be taken to ensure that the RMS current does not exceed that rated current.
